Abstract
Within 30 min of exposure of P388 murine leukemia cells to the anthracycline anti-tumor drug adriamycin, cell-surface electronegativity and incorporation of radioactive fucose into membrane glycoproteins were markedly increased, while cell surface hydrophobicity and incorporation of thymidine into DNA decreased. Incorporation of labeled leucine into cell protein was unaffected. These data indicate a drug-induced increase in production of electronegative and hydrophilic membrane glycoproteins which was not found when adriamycin-resistant cells were similarly treated.
